I believe that client_secret_expires_at was a signal to clients that they 
should plan on retrieving a new client_secret value around that time.  That 
makes sense if you have the management protocol to do so, but I agree with you 
that it isn't very useful without it.  Maybe it should be moved to the 
management spec?

Subject: [OAUTH-WG] client_secret_expires_at in Dynamic Client Registration 
(was Shepherd Writeup for Dynamic Client Registration Draft)

I'm trying to understand the client_secret_expires_at parameter in Dynamic 
Client Registration? It seems rather awkward to have an expiration in this 
protocol that doesn't allow for anything to be done after expiration other than 
doing a whole new registration (and thus losing the client id).

And why does expiration only apply to the client secret? If there's a need for 
expiration, isn't it broader than that and apply to the whole client or the 
client id?

I tried to ask these questions, more or less, in April during last call but 
there was no response:
